Raise Pumparound To Save Energy

Operators are usually more interested in making on-spec products than in saving energy. In the field one will often find pumparound rates cut back to 50% of their proper level. Try increasing pumparound circulation until the product separation is adversely affected. Perhaps an end-pont spec can be extended. Up to the point at which the …

Improper Heat Balance

Hot vapors, flowing up the fractionator from the flash zone, are partially condensed by contact with cooler pumparound liquid. The heat absorbed by the pumparound stream is used to preheat crude. As the pumparound circulation rate is increased, both heat removal from the fractionator and from crude preheat increase. This saves furnace fuel. Higher pumparound …
